Finishing logs

My husband and I live on the Oregon coast. We are in the process of building a new home. We have 4 24 ft, 16 inches in diameter douglas fir logs that we will be using outside to support the overhang over our deck. These logs have had all the bark removed. Can someone please tell me what would be the best way to seal and finish the logs to protect them from the sea air, moisture and sun. We would like to put a clear finish on them so the grain of the wood shows.

There are various oil & waterbased product can use but plan on redoing every couple three years. Some coatings will last long based upon weather conditions still plan on recoating to keep your log looking good. Recommend buying locally if possible.
